I am proofreading my article in UON #27 right now. It is out, but not officially released yet. So once I do that, you will see it come March 2011. Issue #27 is cover-dated January-May 2011.

A word about blitz games. Since the Zilbermints Gambit in the Euwe Defense games are rare, I try to play many Internet Chess Club  games to test critical lines. Even there, not everyone accepts the challenge to play Black. And ICC games comprise the vast majority of my articles! It also means people are more willing to experiment on ICC, since their rating (FIDE or USCF) will not suffer. Outside of ICC, you see few games with the Zilbermints Gambit. Any good database will show you that it is limited at best to fewer than 10 played each year.

While I cannot say that I have every game with the Zilbermints Gambit or its related systems (Clark Gambit, Leisebein-Zilbermints Gambit, Zilbermints Gambit Delayed) my articles represent the first comprehensive effort to organize all known theory and games. The reader will find more than 300 games in the article; an index of variations and players; and a history covering 60 years, 1950 - present.

UON #27 should be coming out next month. It will contain Part 2 of the Zilbermints Gambit in the Euwe Defense to the BDG.

Hopefully UON #27 will come out before this year ends. I plan to publish Volume 2 of Zilbermints Gambit in Euwe Defence there.

Keybook I doesn't provide much analysis. It's just a collection of 700 games with some short comments here and there. As a result it is very unreliable in its evaluations of important variations.
I don't know about Keybook II and II though.
  
The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Well, my first experiments with the 4...h6 line on Internet Chess Club seem to yield decent results.
I will post a few games later. Here is one just to give you an idea:

1 d4 e5 2 dxe5 Nc6 3 Nf3 Nge7 4 Nc3 h6 5 e4 Ng6 6 Qd5 a6 7 Be3 Qe7 8 000 Ncxe5 9 Nxe5 Qxe5 10 Qd2 c6 11 f4 Qa5 12 e5 Bb4 13 Bd4 c5 14 Be3 Bxc3 15 Qxc3 Qxc3 16 bc3 b6 17 a4 a5 18 Bb5 Ra7 19 h4 Ne7 20 g4 Ba6 21 h5 Bxb5 22 ab5 00 23 Rd6 Rb7 24 Rhd1 Rd8 25 f5 Nc8 26 R6d5 Kf8 27 g5 Ne7 28 gxh6 Nd5 29 Nd5 Rh6 30 Bh6+ Kg8 31 Bg5 Re8
32 Bf6 Kh7  33 Kd2 Rg8 34 Ke3 a4 35 Kf4 a3 36 Rd1 a2 37 Ra1 Ra7 38 c4 Rg2 0-1,  beinai (2314 ICC) - Zilbermints (2351 ICC) 10.26.2010, 3-minute rated blitz game

Goldrake, check the Internet! Or buy Tim Sawyer's Blackmar-Diemer Gambit Keybook I (1992) and II (1999). The third edition came out last year, but it is on a CD.

You can also contact me here by email.

Hello,

Time to re-start the thread! 

Blackmar-Diemer Gambit, Euwe Defense:

1 d4 d5 2 e4 de4 3 Nc3 Nf6 4 f3 (BDG) ef3 5 Nxf3 e6 (Euwe)
6 Bg5 Be7  7 Bd3 Nc6 8 00 Nxd4 9 Kh1 ! (the Zilbermints Gambit)

Now it is Black to move. What would you play?



Hi! Where can I find on-line detailed analysis of this opening? Thank you for the answers!

Well, my opponent was not very strong, you see. He was also in time trouble.

Curses!  I hate it when BDG threads are active, because they're so difficult to monitor.  Well, I will just have to live with it, I suppose.

Welcome to the forum, by the way.

P.S.: This thread got started a long time ago, so it still has all caps in some message headers.  Any new post whose subject is in all caps will be summarily deleted, including "Re: {something in all caps}."  I have cleaned up some recent posts in this regard, but I don't intend to do so in the future.

Hi,
This is my first post here. This game was interesting for me on two counts. First, black's advance according to DR4 after 9.Kh1 is 0.59. That in itself is not interesting. But after just the two simplistic exchanging moves 9...Bxc3 and 10...Nxf3 white has full compensation for the pawn.
The second item of interest was the missed wins on both sides. White already mentioned that he missed 15.Qh4. But black missed 18...Be6 with big advantage and 21...Ne4 winning.

I think many of the lines given by Rybka ironically illustrate that computers still have some way to go in handling positions correctly.  In a number of lines it gives Bb5+, then ...c6, and then retreats the bishop to c4 or d3, thereby wasting a tempo (Black often plays ...c6 anyway).

However, upon closer inspection, perhaps I should revise my earlier opinion of 4.f3 Bb4 from "-/+" to "=+", e.g.

A) 5.a3 Bxc3+ 6.bxc3 c5, which I assessed earlier as -/+, but =+ is more in order, e.g. 7.Bf4 Nf6 8.fxe4 Nxe4 9.Qg4 Qf6 with some, but not enough, compensation for White.

B) 5.Bd2 Nf6 6.fxe4 Bxc3 7.Bxc3 Nxe4 8.Nf3 Nxc3 9.bxc3 c5 =+.

C) 5.fxe4 Qh4+ 6.Ke2 Bxc3 7.bxc3 Nf6 8.Nf3 (not 8.e5 Ne4 9.Qe1 Qxe1+ 10.Kxe1 Nxc3) 8...Qg4 9.h3 Qg6 looks =+ to me, despite Rybka's assessment of "=", White's king is trapped in the centre and development is chaotic.  However Black should probably refrain from Fritz 10's tempting preference 7...Qxe4+ 8.Kf2 Nf6 9.Nf3 Qc6 10.Bd3, when White will castle by hand and get some attacking chances in return for the pawn(s).

So perhaps this line is just about playable for White, at least in rapid games, but I maintain that 4...Bb4 is the critical test of 4.f3 (rather than 4...exf3, which is objectively about equal) and I would hesitate to allow that line in a serious game.

According to http://home.lyse.net/chessmaster/BDG_variations.htm the line you mention in the quote above is the Giertz-Peters Gambit. The only difference is that after 4 f3 Bb4 Rybka 2.3.2a gives the following evaluation:

5 fxe4! Qh4+ 6 Ke2 Bxc3 7 bxc3 Nf6 8 Nf3 Qg4 9 h3 Qg6 10 Nd2 Qh5+ 11 Ke1 =

The computer's analyses is found on the website. It gives 4...exf3; 4...Nc6; 4...Nf6 the same evaluation of =

You mean 1 d4 d5 2 e4 dxe4 3 Nc3 Bb4 4 f3?! or 1 d4 d5 2 e4 e6 3 Nc3 Bb4 4 f3?!

Isn't that the Peters-Giertz Gambit?

Which does not address Markovich' point, as he was not writing about that particular game.

That was an over-the-board tournament game, not an ICC game!
